Stroop Test in AJAX

The following is a rough example of the Stroop test, implemented in AJAX. In brief, the theory states that there is extra human coginitive processing power required to choose from a list of random coloured words rather than a list of words which is written in the same colour as the word itself.

The proper Stroop test involves reading the ink colour of words on a printed list, however it is simulated here with a slightly different test

Choose the colour word from the list that is written in the same colour as the word itself.
